STATEMENT OF ANY FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT
The present invention is not subject of Federally-sponsored research or development.
Latin name of the genus and species of the plant claimed The plant claimed relates to a new and distinct variety of Vitis vinifera.
Variety denomination: The plant claimed shall be known as ‘SV35-179-125’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of grapevine botanically known as Vitis vinifera and hereinafter referred to as grapevine named ‘SV35-179-125’. As used herein, ‘grapevine’ refers to all plant parts including, vines, canes, tendrils, leaves, fruit and roots of ‘SV35-179-125’. Grapevine named ‘SV35-179-125’ is the result of an effort to produce an early ripening, black, seedless table grape with fruit characteristics superior to currently available green grape cultivar ‘Summer Royal’ (unpatented). This new cultivar originated from a cross conducted in May 2014 near McFarland, California between female grapevine plant selection ‘SV16-72-83’ (unpatented) and pollen parent grapevine ‘SV21-66-158’ (U.S. Plant Pat. No. 24,510). Resultant ovules from the cross were harvested 42 days after pollination and cultured on ‘Mccown's Woody Plant Medium’. Subsequently, the resultant embryonic plants were cultured in the same medium in the laboratory under twelve hours of light from light emitting diodes at 29° C. The seedlings from this effort were transplanted to the greenhouse in November of 2014 and grown in the greenhouse at 29° C. with 12 hours illumination under high pressure sodium vapor lamps. The seedling population of 90 plants was planted in the field in the spring of 2015 near McFarland, California. The new grapevine was selected from this seedling population on Jul. 2, 2016. It was then propagated by cuttings and bench grafted to ‘Freedom’ (unpatented) rootstock in 2017. The present invention has been found to retain its distinctive characteristics through two successive asexual propagations.
Grapevine named ‘SV35-179-125’ differs from its female parent grapevine ‘SV16-72-83’ (unpatented) in that ‘SV35-179-125’ has ovate shaped, seedless berries whereas ‘SV16-72-83’ has spherical shaped berries with partially lignified seed traces.
Grapevine named ‘SV35-179-125’ differs from its male parent grapevine ‘SV21-66-158’ (U.S. Plant Pat. No. 24,510) in that ‘SV35-179-125’ has ovate shaped, black berries whereas ‘SV21-66-158’ has cylindrical shaped green berries.
Grapevine named ‘SV35-179-125’ differs from the commercial cultivar ‘Summer Royal’ (unpatented) by producing berries which are ovate as opposed to spherical. While both cultivars ripen early in the season, ‘SV35-179-125’ has berries with a mild muscat flavor while ‘Summer Royal’ berries have no muscat flavor.
Grapevine Named ‘SV35-179-125’ is most similar to commercially available cultivar ‘Fantasy Seedless’ (unpatented). Grapevine Named ‘SV35-179-125’ differs from ‘Fantasy Seedless’ by ripening in early July versus September for ‘Fantasy Seedless’ (unpatented) in the McFarland, California area. Grapevine named ‘SV35-179-125’ also produces large, well-filled clusters of berries whereas ‘Fantasy Seedless’ often produces clusters which are not completely filled with berries and having naked rachises.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of the ripe fruit of this new variety when grown under normal horticultural practices near McFarland, California:
- a. Black skinned berries.
- b. Firm berry texture; and
- c. Large, ovate shaped berries with slight muscat flavor.
BRIEF DESCRIPTION OF THE DRAWINGS
This new grapevine is illustrated by the accompanying photographs which show fruit clusters, leaves, canes and tendrils. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken from a plant about 5 years-old, grown in a field near McFarland, California in 2021.

DETAILED BOTANICAL DESCRIPTION
The following detailed description sets forth the distinctive characteristics of grapevine named ‘SV35-179-125’. Descriptions of the new invention apply to vines of grapevine named ‘SV35-179-125’ grown on ‘Freedom’ (unpatented) rootstock at a density of 1,537 vines per hectare grown near McFarland, California in 2011. These vines were in their fifth year of full production having been planted in 2016. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere. Color references are to The Royal Horticultural Society's Colour Chart, The Royal Horticultural Society, London, United Kingdom. Descriptors used herein conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997 which were developed in collaboration with the Office Interantional de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV) and published in Descriptors for Grapevine (Vitis spp.) (Anonymous, International Plant Genetic Resources Institute, 1997, ISBN 92-9043-352-3).
